Usage

update uvm to latest version:

$ uvm update

list all released versions of Golang:

$ uvm go list

list installed versions of Golang:

$ uvm go list --local
  1.20.1
* 1.20.10
  1.21.6

install Golang 1.21.6:

$ uvm go install -v 1.21.6

switch default global Golang version to 1.21.6:

$ uvm go use -v 1.21.6

switch default global Golang version to 1.21.6:

$ uvm go use -v 1.21.6

create a virtual environment with Golang 1.20.1 in current folder:

$ uvm go venv -v 1.20.1

by default this will create a folder named .venv

activiate virtual environment:

$ source ./.venv/activiate.sh
(go)$

deactiviate virtual environment:

$ source ./.venv/deactiviate.sh
$

Node has similar commands.

Java is a little different, each command must specify vendor with --vendor, currently supported vendors includs openjdk, corretto.

for example, install Java 20 from Amazon Corretto:

$ uvm java install -v 20 --vendor corretto

TODO

• configuration for uvm
• support mirrors
• support more languages
• show progress while downloading files
• support more shells for venv
